I've heard both good and bad things about these rings, are these practical for daily driver use in a mild 355ci? thanks in advance for the advice!

We did some testing with the Total Seal rings years ago on the Dyno and did not see the big results as was told by Total Seal so they sent us a new set of rings for the next engine we buillt, same results.
They work fine on leak down tests with some engine shops but we are using the JE file fit rings we see less then 2% leak down after a season of running.
Most performance pistons on the market today have a groove under the top ring and its called an accumulator groove or a pressure seal groove which if there is a small amount of blowby that gets past the top ring there is a place for it to accumulate without affecting the top ring because if there is pressure between the top and second ring it tends to lift the top ring off the ring land causing it not to seal properly.
If those rings were any good the top Cup teams would be using them. My findings are thay are a gimic

Pros:
Leakdowns look good
Cons:
They use oil
They smoke
You will get all woundup when you have to pull the engine to remove them and put some decent rings in
Not a fan of these rings at all, and I've run them 4 times. Each time the block was correctly machined and honed to their specs. Each time they used oil and smoked, even without a pcv system.
It was not going past the seals/guides either. I have spoken with many engine builders since then that all have the same opinion of these rings.

We have worked with both types of rings and for the added cost of the rings and prep work there was no added gains as Total Seal claimed 13 horse over the rings we were using.
We see no signs of blowby under the top ring or out the breathers and the engines leak down less then 2% after a season at the track and the shops that are using cheaper hones and if the cylinders are not quite round at the top you may see more of a gain ???????????

We used the "conventional" Total-Seal rings in the 468" Pump-Gas SB that made 732+ HP and have no problems whatsoever. The customer is using it almost every day up here in N.Y. in the nice weather. We recommended against it, due to the ring sizes, but he's not worried about it. We also have them in a 421" SB (Hi-Comp) that made 738HP, also no problems.Thanks, Gary in N.Y.
P.S. Our first choice is always "Speed-Pro's", but they are very limited in their applications, they just don't always have the sizes we need. We use NO "gapless" rings at all.

I've heard the same Eric, and mine were the second ring gapless. I'm assuming he's talking about gapless rings here; they also make a standard ring set.Eric68 said:
I stick with the Speed Pro Plasma Moly file-fits; seat immediately and always work.

I have used both Total Seal and Childs and Albert gapless rings. I have personally never had a problem with either one. My blower motor has Total Seals in it as well. I never heard anything bad about them until Jody brought it to my attention. I trust Jody's advice/experience, at this point I still haven't had a problem with them. I don't remember which blower company it was, but they recommended using gapless rings (I think it was BDS, not sure though).
I don't understand how they can cause oil usage. The older style ones I could maybe see it. The last set I installed (blown engine) they are basically like a standard ring with an additional ring to make it a gapless ring. I still had to file fit them.
Can anyone explain how thay cause oil usage? I am just curious, if I start having oil usage problems I guess I will look there first.
